The tiff tag summary tab contains information for all tiff tags that appear within the currently loaded x9 file. Each item typically has two attached TIFF images (front and back). Each image has an IFD (Image File Directory) which describes the attributes of the associated TIFF image. There are very specific TIFF tag requirements which are specified in the x9.100-181 standard. This tab allows you to see the various tags that are present across the entire x9 file. This summary includes any errors that are associated with specific tiff tags, and tiff tag consistency across all images that are present across all item images.
